(Cl. 4-Z13) 9Claims.

This invention appertains to ventilated toilets, and is an improvementon my prior Patent No. 2,227,920, issued to me January 7, 1941.

One of the primary objects of my presentl invention is to generallysimplify and reduce the cost of construction of ventilated toilets andto facilitate the installation and incorporation of my Ventilatingsystem with toilets of the type now in common use.

Another salient object of my invention is to provide novel means forutilizing the protecting housing for 'the fan and motor as an entrancechamber for the foul odors from the toilet bowl, and to introduce thesucked-in air from the bowl into the housing insuch a way that the noiseofv the inrushing air will be reduced to a minimum, and the noise of themotor and fan will be muiiled.

Another important object of my invention is to provide positive meansfor preventing the drawing of ushing water into the `protecting housingwith the sucked-in foul air from the bowl.

A further object of my invention is the provision of novel means forleading and forcing the foul odors or gases from the fan into a waterseal ortrap chamber 'to prevent the escape of said gases in such amanner that the size of the water seal or trap chamber can be eectivelyreduced.

Figure i4 is a detail, sectional view taken on the line Il-Il of Figure12, illustrating the formation of the toilet to facilitate the insertionof the vent pipe of the Ventilating system therewith.

Referring to the drawings in detail, wherein similar` referencecharacters designate corresponding parts throughout the several views,the

letter T generally indicates my improved ventilated toilet, whichcomprises a toilet bowl l5 having communicating therewith throughv awater seal or trap I 6 a'drainpipe i1.

The upper end of the bowl il has formed therein a flush ring Il.Thisflush ring has communicating therewith a pluralityof outletapertures Il,` and the flush ring' communicates with `chamber 21.

the main water loutlet20 .of the ush .tank 2|.

This 1outlet'20also communicates with an enthe level of the ushingwaterrin the tank. In kaccordance with my invention, the overow pipe"isbent or has incorporated therein a U-shaped trap portion26 to `form awater seal, for a purpose which will be later set forth.

My device also yincludes a water seal or trap In one form of myinvention, this waterseal or trap chamber 21 is made separate =from thebowl and tank, and with my present construction (as will be .laterdescribed), I am enabled to materially reduce the size of this chamber.Aszillustrated in Figures 1 and 2, the lwaterseal ortrap chamber 21 isarranged in back of thebowl and the outlet or drainpipe |1,and

is ,secured in ,placeby means of a bracket 28.

'Communicating with thechamber 21 is a combined water supply and foulodordelivery pipe 29.

The lower endof `this pipe 23 is bent to form a water trap 30,and thepipe is extended into the trap chamber supply `above the normal waterlevel therein. The pipebelowthe water level has formed therein a smallwater inlet opening 3|,

whereby to insure the correct supplyof water to the trap 30 to.maintain'the seal. Likewise, extending into thetrapchamber 21 above thewater level and above the upper end of the pipe29 is a foul odor drawoif`pipe 32. This pipe isextended into the. drainpipe'H in rear of thewater seal I6 for the bowl. Anypre'ferred type of coupling 32' can beemployed for connecting the pipe 32 with :the toilet. vThe drawoft pipealso has formed therein a small drain opening 33 adjacent the waterlevelin the trap chamber, and, hence, this opening 33'acts to preventthe water from rising Vabove a predetermined normal level in :said 4trapchamber. I

. Inthe flush tankV 2 l, I secure aprotectinghous- ,-ingvor casing 34for the electric motor 35.and the yian 36. The rotor of the fan isdrivenfrom the armature shaft ofthe motor, and ahousing l31 visvemployed for surrounding ithe motor. The motor-and fan are suspended inthe protecting housing or casing 34 by `means of cushioning springs 38,which vare placed at the desired advantageous points. The housing 31 forthe motor is `formed fromicopper or other material which will `quickly`transmit .or .dissipate heat, so that :this housing v31will not becomeunduly heated from theelectric motor 35.

The'pipe 29 is connected to the outlet of the Ian'by theuse ofa suitableflexible coupling, and :the inlet of the fan is adapted to draw air infrom the'housing or casing 34 and to force the air vthrough the pipe L29into the trap chamber 21. This pipe 29 hascommunicating therewithadjacent the bottom .of lthe flush tank 29 the water seal rell tube 39.This tube extends into the water refill pipe 40 for the ilush tank. Thetube 39 .is provided with .an air inlet opening 4| at a point above thenormal Water level in the Yflush tank, and this opening is provided forVbreaking any siphoning action which might take place in said tube. By.this arrangement of parts, the pipe 29, as heretofore stated, is,utilized both for supplying water to the trap chamber 21 and forconducting the foul odors to said trap chamber. Communicating with thetop of the .trap 26 in the overow pipe 25 of the flush tank is the foulodor suction pipe 42. .This suction pipe 42 extends into the bottom of asupplementary foul odor chamber 43, and the upper` end of the chambercommunicates with the housing or casing 34 by means of a plurality ofsmall openings 44.

When the fan is in operation, foul odors will be drawn through the flushring I8, through the opening 20, the overiiow passageway 24, pipe 25,suction tube 42, supplementary chamber A"43, into the housing 34, andinto the fan. As the suction'tube is above the .trap chamber, little orno vwater will be drawn into the supplementary chamber. 43 with the air,and'this chamber functions to collect such ywater and to allow the waterto drain back into the overiiowpipe. The plurality of openings 44distributes theA inrushing air and materially reduces vthe noiseincident to the Ilow of air passing through the fan 36. The housing 34and the chamber 43 also serve as a mufller for reducing noise producedrbythe fan and motor. If desired, the inner face of the housing orcasing 34 can be `provided with a r.lining or skin of -soundprooiingmaterial 45, as

shown in Figure 5 of the drawings. The pipe 29 Vat a desired point inthe housing can be provided with a water drain opening 29' to preventthe collection of any water which might be present in the housing 34.

In use of my toilet, the circuit through the motor 35 is closed by theuse ofa suitable switch mechanism, which is operated preferably by theweight of a person using-the toilet. Asstated, upon the operation of themotor, the fan will suck in air and Vfoul odors from the bowl, 'and thisair is forced through the pipe 29, into the ktrap chamber 21, and thewater inthe trap 3U `provided for resealing the trap 30 with waterwithout the necessity of ilushing thebowl l5, as water will enter thetrap through the opening 3| .from the water supply in the `reservoir`21.

If preferred, water can be supplied to the pipe 29 by means ofaninverted U-shaped tube 46 (see "Figures 7, 8, and 9) in lieu of thetube 39. This tube 46 terminates adjacent the bottom of the ush tank,and any siphoning action inisaid tube 46 will be broken by an `air inlettube 41, which communicateswith the upper bend in said tube, and whichextends above the normal wa- 50 is placed over the inlet of the tube 46in spaced relation to the partition 48. During the intake of water fromthe tube 45 by the pipe 29, the screen will prevent the entrance of sandand the like into saiciV tube, and when the bowl is flushed, the rushingof the water from the flushing tank and the 'drawing of any water inthetube will clean and wash the screen l0..

While I preferto utilize a high speed electric motor and to reduce noiseand vibration by employing cushioning springs, as shown in Figures land2, noise can be reduced to a limited extent by employing a low speedelectric motor, and con-` necting the motor with the fan through a speedincreasing mechanism.

In Figures and ll, I have shown a protecting housing 5I for a. motor 52and a fan 53, and this housing is adapted to be disposed in the flushtankin the same manner as the protecting housing 34. The motor 52 is ofthe low speed type and is secured directly to the housing 5| The fan 53is'held in spacedrelation to the motor by brackets 54. The armatureshaft of the motor has connected therewith a drive pulley 55 of arelatively large diameter, andfthis pulley has trained about the same adrive belt 56. The drive beit is, in tum, trained over a relativelysmall pulley wheel 5l` secured to the drive shaft oi' the 'y rotor o!the tan.y

In,Figures l2 to l4, inclusive, I have-illustrated` a means for formingthe trap or'water seal chamber for the foul odors directly with thetoilet. The rear of the toilet bowl has connected therewith a chamber58, and this chamber communicates with the drainpipe I1 through themedium of an opening 59 in the lower end thereof. A water receivingcompartment 60`open at its top is arranged in the chamber 58. Theconduit pipe 29ffrom the fan is led into the compartment 65, and thisconduit pipe, at 'its lower end, in this form of the invention, isprovided witha U-belt 62. The upper end of the U-belt extends above thewater compartment 50 and is provided with a small opening 63 below thenormal water level in said compartment for insuring the maintenance ofthe water seal in said U-belt. The water compartment Alill acts as areservoir for supplying water through the opening ,63l to the water sealin the U-shaped portion 62 of the pipe 29; I-t can be seen that the foulodors andv air will be forced through the pipe 29 directly into thecompartment Bland then in the drainpipe I1 through the opening 59. Theopening '54 (see Figure 14) for the trap 52 can be of anelongatedcharacter, so as to fa'- cilitate the introduction of the trapinto the water reservoir 50, and` this opening 83 can be closed by theuse of gaskets and the like.
